I'm indebted to Tlaloc for his invaluable recommendations for viewing puzzles like the present "Beginner Puzzle: Klebsiella Pneumoniae" ( http://fold.it/portal/node/989735 ) where you have to match the model to a guide. Working with the guide is much more user friendly when you change your viewing options to these as he has it in his "Technique for Matching a Guide" -- "View the options, turn on 'Show Outline,' set the background color to white, and view stubs on the sidechains, view the guide, and set color relative to guide. Turn all the other view options off."

Perhaps that sentence should be added to the greeting message you get when you start out one of the "easy" guide puzzles. That viewing configuration is so useful for guide work it might even be worthwhile to consider adding a "Guide view options" under "Default view options" in the View Options screen itself.

For those of you who may not already be using these options, here's a screen shot of what it looks like (small mistake, I should have "color relative to guide" of course, but not "fade GUI")
